  • Top 10 Reasons to Choose a Diaphragm Actuated Control Valve

    Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This frequently requires miles of piping mains along with pumps systems and controls that all have to be monitored and controlled somehow. Whether this control is to regulate pressure, a level or a flow, this usually will require some form of a ...

  • Controlling the Flow Capacity of a Metering Pump

    Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute Stroke Length ...

  • What You Need to Know about Electronic Automation of Hydraulically-operated, Diaphragm-actuated Control Valves

    Hydraulically controlled, diaphragm-actuated control valves are the mainstay of the waterworks industry to control pressure, flow, level, pump control, and at times to meter. These automatic control valves are controlled by pilots to do specific tasks and are mainly single-set-point systems. With the need to remotely actuate and control the valves and the applications becoming more complex, ...
